Those yellows are normal. The buds are feeding. If they come off with little effort, that is good!

No it usually doesn't come with the pens gotta buy it separately, keeps the electrode protected so it lasts longer

I'm just worried because top canopy is becoming pale so I upped nutes slightly. But yes, yellowing leaves were basically just falling off as I grabbed a hold of them
I'm by no means an expert, but I don't think your yellowing leaves are normal at this stage of your grow. It looks like a nitrogen deficiency. The bottom leaves falling off and all.

At the risk of going over old ground have you actually flushed your soil? Adding neuts if your roots are locked for specific ones will exacerbate your problem.

Thanks for response... yes, I have actually flushed a few different times at different stages. If it's a nitrogen def it's not enough nitrogen. I went about a month from the start of 12/12 till about a week ago without giving any nitrogen at all besides the miniscule amount that's in my non plant food soil. I fees with gh flora trio

Well I guess my ph better be closer to 7.0 then 4.0 lol...
No. It's already calibrated. Just follow the instructions. Don't stick the whole thing in the water. The same thing happened to me. When it needed calibration I complained and they sent me another meter. About a week later I found the 7.0 pack. Did you get PH down and up?

Nah, mine needs to be calibrated. It is a combo meter. Iv always had ph up and down but I'm just using distilled water. I don't want to be using the salts in the ph up and down

I'm no expert but from videos I have watched and people on this site distilled water or ionized water is what you use

6.5 is around what you want your ph to be but calibrate with distilled water and buffer solution

So for my soil slurry I did 6oz of soil and 12oz of distilled water. Let sit for about an hour then stirred very well. I then calibrated my meter with distilled water and 7.01 buffer solution. I then took a dive into my soil slurry with the electrode sensor and had readings of 7.2-7.4. I also tried an tds reading after calibrating in 1500 ppm buffer solution but my readings were all over the place. Should I only be testing with the tds in my nutrient solution water?

Yeah I don't test ppm in a slurry test, ppm I only worry about whats going in

Also my leaf yellowing may be cause by drastic ph fluctuations. When I tested runoff a few weeks ago with ph drops and color chart my ph red or around 5 ph so I added lime to my soil. Then my new meter came in yesterday and my soil slurry tested on was 7.2-7.4. So I'm thinking I added too much lime and the big ph flucuation shocked my roots causing the yellowing and leaf clawing I am encountering now. OPINIONS????

It's a possibility. Your PH isn't that bad though. A little high...no pun intended. Give it water only next feeding. Soak it and let it drain for a few days to clear out the salts. Not sure if it will help much though.
